This study was conducted to evaluate the relations between alcohol intake and blood lipid level in a group of 1,138 Korean adult men, ages 20 to 69 years. Total number of each of a variety of drinks in the previous two weeks was obtained by questionnaire and converted into grams of alcohol consumed in a week. The levels of blood lipid such as Cholesterol, HDL-Cholesterol, Triglyceride and LDL-Cholesterol were examined by enzyme method. We also observed the effects of various variables such as age, body mass index, smoking, exercise and blood pressure on blood lipid level. The results obtained were as follows; 1. Average weekly alcohol intake was 129.0+/-167.4 gm and that of 30-39 age group was the highest as 149.3+/-170.4gm. 2. Levels of Cholesterol, Triglyceride and LDL-Cholesterol tended to increase with increasing age, but level of HDL-Cholesterol showed no significant relationship with age. 3. The positive linear regressions of alcohol intake on HDL-Cholesterol and Triglyceride were noted statistically significant. 4. Multiple regression analysis demonstrated that the effect of alcohol on HDL-Cholesterol and Triglyceride was statistically significant and the contribution rates were 5.0% and 0.8%, respectively. And, in the case of HDL-Cholesterol, the alcohol intake was the most significant independent variable.

OBJECTIVETo investigate the prevalence and subtype distribution of human papillomavirus (HPV) infection and its correlation with age among women in Beijing urban area, and provide some epidemiological evidence for the clinical application of HPV vaccines.

METHODSWe collected cervical specimens from 1999 women in the Outpatient Department of our hospital, performed genetyping of HPV-DNA, and analyzed the incidence of HPV infection in different age groups.

RESULTSHPV infection was detected in 502 (25.2%) of the 1999 women patients, with 391 (19.6%) cases of high-risk HPV, which included 326 (83.4%, 326/391) cases of single infection. HPV-16 was the most common type (21.2%, 69/326), followed by HPV-52 (19.3%, 63/326) and HPV-58 (16.0%, 52/326). The prevalence of HPV infection was the highest among the women aged 41 -50 years and the lowest among those over 60 years.

CONCLUSIONThe subtype- and age-specific distribution of HPV infection among women in Beijing urban area shows an obvious heterogeneity, which deserves due consideration in the clinical application of HPV vaccines.

ive] To assess the diagnostic value of fiberbronchoscopy for right middle lobe syndrome (RMLS) and to explore the etiology of RMLS. [Methods] Fiberbronchoscopy was carried out in 42 casesof RMLS diagnosed by chest X-ray or CT. [Results] Patients with RMLS due to non-specific inflamma tion accounted for 57.1 % , lung cancer 26.2%and pulmonary tuberculosis 11.9%. Congestion, edema, stenosis, neoplasm, purulent secretion, and mucosa thickening were the main manifestations under fiber-bronchoscope. The diagnostic accordance rate of fiberbronchoscopy for lung cancer, non-specific inflam mation and pulmonary tuberculosis was 90.9% , 87.5% and 60% respectively. No significant differences of the incidences of non-specific inflammation and lung cancer were found in the teenage, the adult and the aged. [Conclusion] Fiberbronchoscopy is an important method of the diagnosis of RMLS. Lung can cer, non-specific inflammation and pulmonary tuberculosis are the common pathogenic factors of RMLS. Male cases over 40 should take fiberbronchoscopy to exclude the possibility of lung cancer.

Femoral head and neck fractures during the course of avascular necrosis are rare with only few reports in the English literature. Moreover, there are very few reports on an analysis of the patterns of these fractures. Four cases of femoral head fracture caused by minor trauma, which were quite different from the crescent fractures during the course of avascular necrosis were analyzed in regard to the underlying disease, causes, sites, types, directions, pattern of fractures and the injury mechanism of the fractures. The results are reported with special regard to the pattern of the stress fracture of the femoral head and neck during the course of avascular necrosis.

Objective To investigate the epidemiological characteristics of human brucellosis in Ulanqab of Inner Mongolia.Methods Three hundred and twenty patients with suspected brucellosis were selected,who had registered in the Ulanqab Center for Endemic Disease Control of Inner Mongolia from April to June 2011.The investigation covered general situation,such as gender,age,occupation and main clinical symptoms and so on.Blood samples were collected,and Rose Bengal plate agglutination test(RBPT) was used for serum screening.Those who were tested positive in RBPT were confirmed with tube agglutination test (SAT).Brucellosis was diagnosed according to Diagnostic criteria for Brucellosis (WS 269-2007).Data were analyzed with statistical software(SPSS 17.0).Results One hundred and thirty-four cases were positive in RBPT of the 320 people surveyed,of which 93 cases were positive in SAT; antibody titers were higher than 1 ∶ 100(++),therefore they were diagnosed as brucellosis,and the ratio was 29.1％(93/320).The number of patients with suspected brucellosis who were negative in SAT test was 41,and the ratio was 12.8％ (41/320).Among the 93 people who were infected,the constituent ratio of farmers and herdsmen who engaged in livestock was the highest,accounted for 63.4％(59/93) and 24.7％ (23/93) of the total number of patients ; infection rate of male (30.9％,55/178) was higher than that of females (26.7％,38/142) ; the number(39) of brucellosis patients who were over the age of 51 was the highest,and the ratio is 42.0％.The onset season mainly in May and August; main route of exposure was bare hands lambing,midwifery and contact with infected sheep pollutants.Conclusions Sheep is the main source of human Brucella infection in Ulanqab.It is the key to control the spreading of brucellosis through improving awareness of disease prevention among farmers and herdsmen as well intensifying the prevention and control of Brucella infection between livestock.

Objective To evaluate the effect of multiplex polymerase chain reaction(Multiple-PCR) in identification of Brucella strains.Methods Six standard Brucella strains (Brucella abortus,Brucella melitensis,Brucella suis,Brucella canis,Brucella ovis,Brucella neotomae) were used as positive controls and Escherichia coli O∶157 and Yersinia enterocolitica O∶9 were used as negative controls.A total of 29 Brucella strains were tested.Brucella strains were amplified by BCSP31-PCR and the species of Brucella with positive results were identified with Multiple-PCR method.Results The results of all 29 amplified Brucella strains were positive with BCSP31-PCR.The identified results of all Brucella strains were positive with Multiple-PCR,including 20 strains of Brucella melitensis,5 isolates of Brucella suis,3 strains of Brucella abortus and 1 strain of Brucella canis.Conclusion Multiple-PCR method is a rapid,specific,simple and low risk method for identification of Brucella species.

We evaluated the accuracy of a noninvasive method for estimating right ventricular systolic pressures in patients with atrial septal defect and tricuspid regurgitation defected by two-dimensional and Doppler ultrasound. Of 54 patients with atrial septal defect, 24(44%) had jets of tricuspid regurgitation. By use of the maximum velocity(V) of the regurgitatant jet recorded by continuous wave Doppler ultrasound and the Bernoulli equation, we predicted right ventricular systolic pressure(RVP) calculated by the equation of RVP=4V2+10 proposed by Tei et al.The values correlated well with catheterization values(r=0.851, standerd error of estimate=4mmHg). In addition the relation between the Lt to Rt shunt amount and the severity of tricuspid regurgitation was assessed. The severity of tricuspid regurgitation graded on a four-pointscali by pulsed Doppler and two-dimensional echocardiography correlated with Qp/Qs ratio calculated by the Fick's method(p<0.05).
